Ecological succession
- It is a gradual process by which ecosystems undergo changes and develop over a period of time.
- The changes in an ecosystem occurs as a result of interaction between organisms and the environment through processes such as growth and reproduction.
<h3>Types of Ecological succession;
</h3><h3>Primary succession
</h3>
- This is a type of succession that takes place in lifeless areas as a result of disturbances such as glaciers, lava flow from volcanoes, sand dunes, etc.
- These regions are not capable of sustaining life of organisms as a result of the disturbances caused by those factors.
<h3>Secondary succession
</h3>
- Secondary succession is an ecological succession that results from disturbances such as forest fires, abandoned field or after occurrence of floods.
<h3>Differences between secondary and primary succession </h3>
- The difference between the two types of ecological succession is the fact that; primary succession starts with bare rocks while secondary succession starts with existing soil and dirt.
- Additionally, it takes about a thousand years for primary succession to develop while secondary succession takes about a 100 or more years to develop.

Answer:
b. Everything in the Universe is connected in some way
Explanation:
Carl Sagan stated "If you want to make an apple pie from scratch, you must first invent the universe." With that, he affirmed that everything we know and that we own is used through a series of products that in a connected and organized way originates from a common point. That point is the universe.
For Carl this is justified, because to make an apple pie, you need to have ingredients. The ingredients were supplied by the work of the industries, the industries needed the agricultural products. Agricultural products needed a plant, the plant needed other things, it needed other things, and so on.
In this way we can confirm that Carl meant that everything in the universe is connected.
The connection between the nose and the brain are governed by our sensory motor cells and neurons. Our senses (including the nose) send signal to our brain through the neurotransmitters. Similarly, the brain sends feedback to other senses and organs through the same media. This explains the unpleasant feeling we get when we smell something foul.
